Anxiety and depression in cancer patients during the course of radiotherapy treatment

Undergoing radiotherapy is often associated with severe impairment of quality of life in cancer patients. Especially psychosocial aspects like anxiety and depression play a major role. The aim of this study was to closely analyze anxiety and depression during the course of radiotherapy treatment. A total of 60 patients, who received radiotherapy because of a tumor disease between June 2005 and April 2006, were included in the prospective study; 57 (95%) patients were primarily treated with radiotherapy. In 72% of the cases the intention to treat was curable, in 18% palliative. Anxiety and depression (HADS-D) were assessed at three points in time: before (A) and after (B) radiotherapy treatment (RT), and 6 weeks after finishing RT at the follow-up appointment (C). Before therapy (A), 41% of the treated patients showed positive or marginally positive symptoms of anxiety and 33% symptoms of depression. The symptoms of anxiety significantly decreased during the course of therapy. The proportion of patients with a positive score of anxiety dropped from 16% at the beginning of RT (A) to 9% after the RT (B; p = 0.04). In addition, there was an increase in the number of patients who scored negatively with regard to anxiety from 59% (A) to 72% (B; p = 0.04). With regard to the median score of anxiety, no statistically significant change (p > 0.05) was observed during therapy, while for depression, the number of positively tested patients also decreased significantly during the course of therapy from the beginning of RT (A, 14%) to the first follow-up appointment (C, 9%; p = 0.02). Furthermore, the number of negatively tested patients rose by 8% (p = 0.02). During the whole course of the study, the median score of depression decreased from 6 (A) to 5 points (C; p = 0.01). More than one third of the treated patients suffered from positive or marginally positive symptoms of anxiety and depression. This present study showed a decrease of anxiety and depression symptoms during the course of radiotherapy.
